This is signified by the intertwined appearance of their Mangekyō Sharingan's tomoe seals, with traits of the donor's tomoe merging with those of the eyes' new host. Due to the strict compatibility issues and the Mangekyō Sharingan's rarity, not everyone can gain these benefits by transplanting the eyes of just any Uchiha, which has been the cause of many fruitless sacrifices throughout the Uchiha clan's history. Thus far, only Madara and Sasuke are known to have been successful in this endeavour.

[[Itachi Uchiha]] gainedthe Mangekyō Sharingan byaiding his best friend, [[Shisui]], inkillinghimself.<ref>''Naruto'' chapter 550, page 11</ref> With the Mangekyō Sharingan, Itachi was able to use at least three powerful techniques. With his "left Mangekyō" he could use [[Tsukuyomi]], an extremely powerful [[genjutsu]] that allowed him to distort the victim's perception of time, torturing their psyche for what seemed like days in a matter of seconds. With his "right Mangekyō" he could use [[Amaterasu]], a [[ninjutsu]] which createsvirtually-inextinguishable black flames at the user's focal point thatcontinuetoburnuntilthetargetis reduced to ash.

Use of the Mangekyō Sharingan put a great strain on Itachi's body and would quickly deplete his chakra reserves to the point that after using it three times in a day, he deactivated his eyes to their normal state.<ref>''Naruto'' chapter 148, page 7</ref> A [[Shapeshifting Technique|clone]] containing 30% of his chakra couldn't use it once. By the time he battled Sasuke, his sight had been reduced to a large blur, yet having resolved himself to dying at the hands of his brother, pushed past this limitation and used his Mangekyō Sharingan more than three times as well as other techniques. After being reincarnated by the [[Impure World Reincarnation]] technique, Itachi was able to use the Mangekyō Sharingan for extended periods of time without complaints of physical ailments, or deteriorating vision. Some time after his death, Sasuke eventually took Itachi's Mangekyō Sharingan as his own, granting him an Eternal Mangekyō Sharingan.

=== Kakashi Hatake ===

−

[[Kakashi Hatake]]'s Mangekyō Sharingan awakened, after the trauma of killing [[Rin Nohara]] with his own hands.<ref name="chpt605"/> Despite its awakening, Kakashi only began to use the Mangekyō during Part II of the series, whether he knew he possessed it beforehand is unknown. Regardless, with this dōjutsu Kakashi can use a space–time ninjutsu known as [[Kamui]] to create a barrier and send a target to the [[other dimension]] and afterwards teleport them back in a new location. The barrier requires considerable effort to aim with precision, leaving Kakashi's chakra significantly drained; especially considering that Kakashi is a non-Uchiha. Initially, he could only handle two uses in a single day, left crippled for over a week from a third use,<ref>''Naruto'' chapter 278, pages 6-7</ref> and had poor control at aiming it.<ref>''Naruto'' chapter 276, page 10</ref> However, after much practice, he can now even control the size of it to only affect the target he chooses, and use precise aim to warp speeding targets.<ref>''Naruto'' chapter 424, pages 16-17</ref> He can also use it twice in quick succession, without showing immediate chakra drain and fatigue, to counter [[Sasuke Uchiha]]'s [[Susanoo]] arrows.<ref>''Naruto'' chapter 484, page 6</ref> By the time of the [[Fourth Shinobi World War]], Kakashi became able to use it several more times in a single day, even with multiple other chakra-taxing techniques, and recover from an over-usage much quicker. His skill has grown to the point that he can use this technique on himself.<ref>''Naruto'' chapter 608, pages 3-7</ref>

=== Obito Uchiha ===

=== Obito Uchiha ===

−

After witnessing [[Rin Nohara]] dying at Kakashi's hands, [[Obito Uchiha]] awakened his Mangekyō Sharingan.<refname="chpt605"/> As the two share the same pair of eyes, Obito's Mangekyō Sharingan also allows him to use [[Kamui]], although his version differs from that of Kakashi's. Whereas Kakashi's version works on targets from a distance, Obito's version requires him to first make physical contact with a target besides himself and afterwards, he can teleport the target back from the other dimension. In addition, Obito's version gives him a form of "''intangibility''", brought about by him teleporting portions of his body for short periods of time to the other dimension in order to avoid damage or pass through obstacles. This also provides Obito immunity from Kakashi's Kamui being used directly against him since they both access the same dimensional space, though attacks being warped by Kamui to the other dimension can bypass Obito's intangibility.<ref>''Naruto''chapter 599, page 8</ref> He can also combine the spatial distortion of the Kamui with his [[Fire Release]] techniques to create a [[Fire Release: Blast Wave Wild Dance|massive vortex of flames]].

<spanid="Kakashi Hatake"> </span>

[[Obito Uchiha]] awakened his Mangekyō Sharingan after the death of [[Rin Nohara]] during the [[Third Shinobi World War]]; Obito himself only had his right eye at the time, but the event caused his Mangekyō to simultaneously awaken in [[Kakashi Hatake]], who wielded Obito's left eye.<ref name="chpt605">Chapter 605, page 4</ref> Both eyes have access to [[Kamui]], able to teleport targets to and from [[Kamui's Dimension]] though in different manners. The right eye is able to use close-range Kamui, teleporting the user or those they're in contact with. By teleporting only parts of their body there, they can in effect seamlessly pass through other matter. The left eye is able to use long-range Kamui, creating a barrier around a target that teleports them.<ref>Chapter 276, page 10</ref> The left eye can also target the user themselves.<ref>Chapter 608, pages 3-7</ref> During the [[Fourth Shinobi World War]], it was discovered that each eye is impervious against the others' Kamui.

+

+

[[Madara Uchiha]] steals Kakashi's eye in order to pursue Obito to Kamui's dimension. There, he exchanges the eye for Obito's [[Rinnegan]], returning both eyes to their original owner, who was currently [[Body Coating|possessed]] by [[Black Zetsu]]. During this brief period, Black Zetsu also gained access to both Sharingan powers. After Obito was freed from Black Zetsu's control, he uses them in combination effectively thereafter, but the eyes are destroyed when he is killed by [[Kaguya Ōtsutsuki]]'s [[All-Killing Ash Bones]]. His spirit briefly returns to the living plane and inhabits Kakashi, giving him both Mangekyō's with their respective abilities and, by extension, [[Susanoo]].

Sasukehas been shown using the same Mangekyō Sharingan techniques as Itachi, but in an inverted manner. With his "right Mangekyō" he can use [[Tsukuyomi]]tobreaka target's will and paralyse them.<ref>''Naruto'' chapter 408, page 4</ref> [[Danzō Shimura]] stated that Sasuke's version is not yet capable of altering the victim's perception of time, and thus is vastly inferior to Itachi's.<ref>''Naruto'' chapter 478, page 3</ref> With his "left Mangekyō"hecanuse[[Amaterasu]]. It has been implied that his skill with Amaterasu surpasses Itachi's, as he is able to use [[Blaze Release: Kagutsuchi]] with his "right Mangekyō" to apply [[Shape Transformation]] to the flames, as well as extinguish them at will. Sasuke has displayed the ability to use [[Susanoo]], which he can even partially manifest to fit the situation, such as using a ribcage for defence or manifesting only an arm to interact with his surroundings. Sasuke's Susanoo develops in stages during various battles; he first starts using an incomplete version against the [[Fourth Raikage]], develops a version capable of firing arrows while fighting with Danzō, and later forms a version almost identical to Itachi's during his battle with Kakashi. Sasuke's Susanoo appears more demonic than Itachi's.

Afteracquiring the [[SixPathsYinPower]], Sasuke's left Mangekyō Sharinganevolvedfurtherinto a unique version of the Rinnegan.

Duetohishigh chakra reserves, Sasuke is able to use the Mangekyō Sharingan techniques more than three times a day. Sasuke can maintain Susanoo for extended periods of time, on top of using the Amaterasu and Tsukuyomi several times a day along with some other chakra-consuming techniques like the [[Chidori]]. Like with all other wielders, Sasuke's use of the Mangekyō Sharingan puts a great strain on Sasuke's body and eyes.

[[Shisui Uchiha]] awakened his Mangekyō Sharingan through unknown means. With each of his eyes he could use [[Kotoamatsukami]], a powerful genjutsu that manipulates a target's thoughts completely without any, including the target, having the slightest idea that they were being controlled. However, this technique can't be used with the same eye again until after a prolonged period of time.<ref>Chapter 550, page 12</ref> In the [[Ninja Escapades|anime]], awakening the Mangekyō Sharingan in both eyes allowed him to use [[Susanoo]].

The Mangekyō Sharingan (万華鏡写輪眼, Literally meaning: Kaleidoscope Copy Wheel Eye) is an advanced form of the Sharingan that has only been activated by a handful of Uchiha.[1] They are noted to be the "heavenly eyes that see the truth of all of creation without obstruction" (天壌の理を掌握せし瞳, tenjō no kotowari o shōaku seshi hitomi).[2]

Contents

A Mangekyō Sharingan is distinguished from a normal Sharingan by its appearance, which changes the form of the tomoe seal. The exact design differs from user to user, though all resemble pinwheels. It is initially awakened by the trauma suffered from witnessing the death of someone close to the user. Uchiha have historically misunderstood this criteria as the user needing to be responsible for the person's death, and for that reason they developed the practice of killing their closest friends in order to gain the Mangekyō Sharingan.[3]Obito's Mangekyō activated immediately after his trauma, whereas, in Naruto Jinraiden, Sasuke's Mangekyō didn't activate until several weeks afterwards.

The Mangekyō Sharingan retains all of the Sharingan's generic abilities, such as casting genjutsu and the ability to distinguish chakra. In addition to these, the Mangekyō grants powerful abilities that differ from user to user, though abilities may be similar in nature; both Sasuke and Itachi have access to Amaterasu's flames, though the extent to which they can use them differ. The abilities of a Mangekyō Sharingan may not even be the same for both of a single user's eyes, as Itachi has Amaterasu in one eye and Tsukuyomi in another. Once a user unlocks the ability of both of their eyes, they are able to perform Susanoo.

The Mangekyō Sharingan's abilities drain a considerable amount of chakra when performed. Its usage and activity also place a great strain on the user themselves and over time deteriorates their vision until they are finally left blind.[4] Their vision can be restored by receiving the transplanted Mangekyō of an Uchiha with strong blood ties — ideally a sibling — thus awakening so-called Eternal Mangekyō Sharingan (永遠の万華鏡写輪眼, Eien no Mangekyō Sharingan).[5] The Eternal Mangekyō merge the designs of the transplanter and the transplantee's original Mangekyō. Their Mangekyō-based abilities are made stronger and they no longer suffer any negative side-effects from the usage. According to Madara, the Eternal Mangekyō Sharingan is proof an Uchiha continues to seek something despite experiencing great losses.[6] In addition to the unique techniques, there are apparently variants of the Eternal Mangekyō Sharingan, one being the "straight tomoe" (直巴, Choku Tomoe), which seems to grant the user fluidity in their movements when fighting.[7]

As with any dōjutsu, Mangekyō Sharingan can be transplanted into non-Uchiha, granting them all its abilities albeit with steeper chakra demands. (In the case of eyes transplanted for the Eternal Mangekyō Sharingan, abilities are not transferred.) Abilities of a Mangekyō Sharingan can also be programmed to activate under certain circumstances, either within the user's own eyes or in a target of the user's choosing; this programming remains even after death.[8]

Itachi Uchiha awakened his Mangekyō Sharingan after witnessing the suicide of his best friend, Shisui Uchiha, shortly before the Uchiha Clan Downfall.[9] With his left Mangekyō he can use Tsukuyomi, an extremely powerful genjutsu that distorts the victim's perception of time. With his right Mangekyō he can use Amaterasu, creating inextinguishable black flames at the user's focal point. Because awakened both his Mangekyō, he can use Susanoo. Use of the Mangekyō is particularly debilitating for Itachi, such that after using it three times in one day he can no longer keep even his normal Sharingan active.[10] Some time after Itachi's died, desiring the power to kill Naruto, Itachi's brother, Sasuke Uchiha, had Itachi's eyes transplanted into him.

Obito Uchiha awakened his Mangekyō Sharingan after the death of Rin Nohara during the Third Shinobi World War; Obito himself only had his right eye at the time, but the event caused his Mangekyō to simultaneously awaken in Kakashi Hatake, who wielded Obito's left eye.[11] Both eyes have access to Kamui, able to teleport targets to and from Kamui's Dimension though in different manners. The right eye is able to use close-range Kamui, teleporting the user or those they're in contact with. By teleporting only parts of their body there, they can in effect seamlessly pass through other matter. The left eye is able to use long-range Kamui, creating a barrier around a target that teleports them.[12] The left eye can also target the user themselves.[13] During the Fourth Shinobi World War, it was discovered that each eye is impervious against the others' Kamui.

Madara Uchiha steals Kakashi's eye in order to pursue Obito to Kamui's dimension. There, he exchanges the eye for Obito's Rinnegan, returning both eyes to their original owner, who was currently possessed by Black Zetsu. During this brief period, Black Zetsu also gained access to both Sharingan powers. After Obito was freed from Black Zetsu's control, he uses them in combination effectively thereafter, but the eyes are destroyed when he is killed by Kaguya Ōtsutsuki's All-Killing Ash Bones. His spirit briefly returns to the living plane and inhabits Kakashi, giving him both Mangekyō's with their respective abilities and, by extension, Susanoo.

Madara Uchiha was the first Uchiha to awaken the Mangekyō Sharingan.[14] His are the "straight tomoe" variety of Mangekyō, granting him superior movement-reading capabilities. It's not known what the individual abilities of each of his eyes were, but he was able to use Susanoo. When Madara's over-usage of his Mangekyō during the Era of Warring States left him blind, this prompted his brother, Izuna Uchiha, to bequeath Madara his eyes on his deathbed for the sake of preserving the Uchiha, thus granting Madara the Eternal Mangekyō Sharingan.[15]

Towards the end of his life, Madara was able to evolve his eyes into Rinnegan, which he transplanted to Nagato before his death. The eyes eventually find their way back to Madara after he is revived.

Izuna Uchiha awakened his Mangekyō Sharingan shortly after Madara did.[14] It's not known what the individual abilities of each of his eyes were. Before he died, Izuna entrusted his eyes to Madara in order to restore his vision and thus protect the Uchiha from extinction.[15] Despite Izuna giving the eyes willingly, Madara is popularly believed to have taken the eyes against Izuna's will.[14]

Sasuke Uchiha awakened his Mangekyō Sharingan after the death of his older brother, Itachi Uchiha. His are the "straight tomoe" variety of Mangekyō, granting him superior movement-reading capabilities. With his left Mangekyō he can cast Amaterasu. With his right Mangekyō he can shape the flames or extinguish them. Because he awakened both of his Mangekyō, he can use Susanoo. Sasuke is initially reluctant to transplant Itachi's eyes and gain the Eternal Mangekyō Sharingan, claiming that his views were different from Itachi's. Later, he decided he needs the increase of strength in order to kill Naruto Uzumaki.

After acquiring the Six Paths Yin Power, Sasuke's left Mangekyō Sharingan evolved further into a unique version of the Rinnegan.

Shisui Uchiha awakened his Mangekyō Sharingan through unknown means. With each of his eyes he could use Kotoamatsukami, a powerful genjutsu that manipulates a target's thoughts completely without any, including the target, having the slightest idea that they were being controlled. However, this technique can't be used with the same eye again until after a prolonged period of time.[16] In the anime, awakening the Mangekyō Sharingan in both eyes allowed him to use Susanoo.

When Shisui attempted to use Kotoamatsukami in order to avert the Uchiha Clan Downfall, his right Mangekyō was stolen by Danzō Shimura, who felt Shisui's plan was futile and wished to protect the village in his own manner. Fearful that Danzō would take his other eye too, Shisui entrusted it to his best friend, Itachi Uchiha, and begged him to use it to save Konoha.[17] Danzō transplants the eye he took into himself and uses it over the years to manipulate others to his way of thinking, using the power of Hashirama Senju to reduce its recharge time. Danzō destroys the eye before his death so that nobody else could have it.[18] Itachi transplanted the eye he was given into a crow that he planned to use to re-ally his brother, Sasuke, with Konoha.[19] He unintentionally used it on himself instead when he is reincarnated in order to break free of Kabuto Yakushi's control. Itachi incinerates the crow afterwards so that nobody else could have the eye.

Originally in the anime, Itachi Uchiha was shown using techniques exclusive to the Mangekyō Sharingan without having it active.[24] This is because Kishimoto had not revealed the appearance of the Mangekyō Sharingan in the manga yet. A true form of the Mangekyō Sharingan was first seen, from Itachi, while Sasuke remembered the events leading to the Uchiha Clan Downfall as he fought with Naruto Uzumaki at the Valley of the End.[25]

Despite using his Mangekyō extensively for over a decade, Obito never displayed any signs of fatigue or deteriorating eyesight.

The manners in which an individual gains the Mangekyō Sharingan are almost parallel to how an Uchiha awakens their regular Sharingan for the first time, since both need intense emotions to awaken them.

In the manga, Sasuke Uchiha's Mangekyō Sharingan is the only one with an inverted colour scheme, boasting a red design and black sclera.
